Is AD 2013-18-07 a recurring Airworthiness Directive?

No — AD 2013-18-07 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2013-18-07 apply to?

AD 2013-18-07 applies to Bell — models 204B, 205A-1, 204, 205. Serial/part conditions may narrow it to specific aircraft.

What this AD requires

We are superseding revised Airworthiness Directive (AD) 76-12- 07 for all Bell Model 204B and certain serial-numbered Model 205A-1 helicopters with a certain tail rotor pitch control chain (chain) installed. AD 76-12-07 required visually inspecting the chain to detect a crack in the link segments and, for affected Model 205A-1 helicopters, replacing the chain and cable control system with a push- pull control system. This new AD requires, for Bell Model 204B, inspecting certain chains at specified intervals, revising the inspection procedures, installing a tail rotor cable and chain damper kit (damper kit), and revising the maintenance manual or Instructions for Continued Airworthiness (ICAs) to include the inspection intervals. This new AD also requires, for certain Bell Model 205A-1 helicopters, replacing the chain and cable control system with an airworthy tail rotor push-pull control system kit. This AD was prompted by the rapid growth of a crack leading to premature chain failure. The actions are intended to prevent failure of the chain, loss of tail rotor blade pitch control, and subsequent loss of control of the helicopter.

Serial-conditional — narrows to serials 30001–30228.

Part-conditional — 204-001-739-003, 204-001-739-105.

Applies to Model 204B helicopters with tail rotor pitch control chain P/N 204-001-739-003 or -105 installed, and Model 205A-1 helicopters with serial number 30001 through 30228.

Whether AD 2013-18-07 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 2013-18-07 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
